Physics Labs with Computers, Vol. 1Student WorkbookP11: Collision – Impulse and Momentum 012-07000AAnalyzing the Data1. Zoom in about the peak in the force vs. time plot.• In the Graph display, click on the zoom button ( ). While holding down on the mousebutton, move the cursor to draw a rectangle around the peak in the force vs. time plot.Make sure that the entire peak is in the rectangle. Result: The points will be highlighted.Release the mouse button and the Graph axes will rescale to zoom in about the region.2. Select the region in the graph window that corresponds to the collision.• Hold down on the mouse button and move the cursor to draw a rectangle around the regionof the force vs. time plot that shows the collision. Release the mouse button, and the areawill be highlighted.3. Integrate to find the area under the curve.• In DataStudio, click the ‘Statistics’ menu button ( ) and select ‘Area’.• In ScienceWorkshop, click the Statistics button ( ) to open the Statistics area on the rightside of the graph. In the Statistics area, click the ‘Statistics Menu’ button ( ) andselect ‘Integration’.4. Record the value of the area under the curve in the Data Table in the Lab Report section.5. Find the velocity just before the collision and the velocity just after the collision from thevelocity versus time plot.• In DataStudio, select the velocity window. Click the ‘Smart Tool’ button ( ) and movethe Smart Tool to the velocity data points. If needed, zoom in about the region duringwhich the collision took place using the zoom tool.• In ScienceWorkshop, click the ‘Smart Cursor‘ ( ) and move the Smart Cursor to thevelocity data points. If needed, zoom in about the region during which the collision tookplace using the zoom tool.6. Record the two velocity values in the Data Table in the Lab Report section.7. Use the mass and velocity values to compute the momenta before and after the collision.Record your results in the Lab Report section.p. 72 ©1999 PASCO scientific P11
